NoviceDev — Thu, 19 Jan 2023 03:45:50 +0000

Are you looking to update your Homebrew and its packages on your mac? It's an easy process and can be done in just 2 steps.

Step 1: Brew update

First, open up your terminal and type in the following command: "brew update". This will update the homebrew and it should always be run before installing or updating any package with brew.

$ brew update
Updated 2 taps (homebrew/core and homebrew/cask).

How to Create a new GIT Branch from a Tag?

NoviceDev — Tue, 27 Sep 2022 07:50:55 +0000

A new GIT branch can be created from a tag through the “git checkout” command with the “-b” option followed by a new branch name and tag name.

$ git checkout -b <new-branch> <tag-name>

Why Create Git Branch from a Tag

GIT tags are created to mark a specific point in git history and then deployed. But sometimes you might want to debug the deployed code and the best way is to create a new GIT branch from that tag.

How to Create Git Branch from a Tag

Let’s say you have deployed tag v2.0 on production and now you have some issues after the deployment.

Now creating a debug branch from the tag v2.0 will be the best way to make sure you have the exact code which is deployed on production.

Now let's go through each step one by one to create a new branch from the correct tag.

1. Get the tag

Make sure you fetch all the tags from your remote repository with the "git fetch" command

$ git fetch --all --tags

2. Confirm the tag

Now confirm that you have fetched the required tag v2.0 from which you want to create the branch.

$ git tag -l

v2.0
v1.0

3. Create a new branch from the tag

After confirming that tag v2.0 fetch properly, we can now run the "git checkout" command to create the new branch from that tag.

$ git checkout -b debug-tag-2-0 v2.0

Now we have a new branch "debug-tag-2-0" ready for debugging on local.

Conclusion

In this tutorial, we learned why we might need to create a new git branch from a tag for debugging and how this can be achieved with the "git checkout" command.

How to Create a Branch in GIT?

NoviceDev — Tue, 27 Sep 2022 07:32:34 +0000

Whenever you start developing a new feature you must start with creating a new branch git. This way you separate your feature changes from other branches.

A new branch can be created with the ‘git checkout’ command with ‘-b’ and a new branch name as arguments. This will create a new branch from your current branch.

$ git checkout -b <new-branch>

But if you don't want to create a new branch from the current branch then you can also pass the base branch as an argument.

$ git checkout -b <new-branch> <base-branch>

This new branch can be merged back into the other branch once the feature is completed.

Create a GIT branch from the master branch

Let's take an example, you want to create a new feature branch 'feature-2' from the master branch.

1. Checkout master branch (source branch)

First, make sure your current git branch is the master branch. You can check this by running "git branch" or "git branch --show-current" commands

$ git branch

  feature-1
* master

If not, then make sure to checkout the master branch.

$ git checkout master

2. Run "git checkout" command with "-b" and feature branch name

Now you can run the GIT checkout command to create a new feature branch "feature-2"

$ git checkout -b feature-2
Switched to a new branch 'feature-2'

Once run successfully, the new branch will be created and your current branch will be switched to this new branch.

3. Confirm the new branch

You can also verify your new branch by running the ‘git branch’ command.

$ git branch

  feature-1
* feature-2
  master

Conclusion

In this tutorial, we learned to create a new branch in GIT with the "git checkout" command. This can also be achieved with the "git branch" command.

A GIT branch is not the only source for creating a new feature branch. A New GIT branch can also be created from commit SHA, a tag, or a remote branch.

Create GIT Branch from a Commit

NoviceDev — Tue, 13 Sep 2022 01:51:27 +0000

Usually, a branch is created from another branch which is the latest HEAD commit of the branch. But what if you want to create a branch from a previous commit HEAD?

GIT branch can be created with a commit hash using the ‘git checkout’ command with ‘-b’ option and then pass a new branch name with the commit SHA.

$ git checkout -b <new-branch> <commit-sha>

Or, you can also use the 'git branch' command to create the branch without switching to the new branch.

$ git branch <new-branch> <commit-sha>

Here are the detailed steps to create a GIT branch from a commit hash with the git checkout command:

1. Find commit SHA with git log

The first step is to find the commit SHA from which you want to create the branch.

Use ‘git log’ command with ‘--online’ and ‘--graph’ options to get the commit SHA.

$ git log --oneline --graph

* 39710b8 (HEAD -> feature-2) Feature 2 added.
* ecddf76 Feature 1 added.
* 34cd5ff (new-branch, develop) Test commit.

Now you can see 3 commits in the git history.

2. Create new branch from commit SHA

Now let's assume you want to create a branch from the second commit with commit hash value 'ecddf76'.

$ git checkout -b feature-102 ecddf76

3. Confirm new branch head

Use 'git log' command again to make sure that the new branch is created from the correct commit SHA

$ git log --oneline --graph

* ecddf76 (HEAD -> feature-104) Feature 1 added.
* 34cd5ff (new-branch, develop) Test commit.

Now you have successfully created a new branch from a commit in the commit history.

How to rename git branch?

NoviceDev — Sun, 30 Jan 2022 14:53:04 +0000

Made a small mistake while naming your git branch, don't panic this blog post will go through all the possibilities for renaming the git branch on local and remote.

Git branch can be renamed with a simple command "git branch -m ", this will rename your current git branch name. Once the branch is renamed on local you can push the new branch to remote and delete the old git branch on the remote.

Now let's go through some detail on why and how to rename a git branch on local and remote.

Why you might want to rename the git branch name?

Before going into details of how to rename local and remote git branches, let's see the reason why you might want to do it:

You might want to rename your git branch if the branch name does not match your project branch naming standards.
You might have the wrong branch name or a wrong ticket number in your branch name.
Sometimes you might make a typo mistake while naming your branch and want to make it perfect by renaming it.

How to rename the local git branch?

Now let's see how to rename a git branch on local with these steps:

The first step to rename a branch is to checkout the branch you might want to rename.

$ git checkout <old-name>

Now you can run the "git branch" command with -m and the new branch name

$ git branch -m <new-name>

To check if the branch is renamed correctly you can run the "git branch" or "git status" command to check your current branch

$ git branch

$ git status
On branch new-name
nothing to commit, working tree clean

If your old git branch was only on your local and not pushed to remote then you can stop here.

But if you have the wrong branch name on remote as well then continue reading.

How to rename remote git branch?

In the previous stage, we rename the git branch on local and now we will follow these steps to update the branch name on remote as well.

Once the branch is renamed on local, run the below command to push the renamed branch to remote

$ git push origin -u <new-name>

Pushing the branch to remote with the new name will now delete the old branch on the remote. You need to run the below command to delete the remote branch with the old name.

$ git push origin --delete <old-name>

Conclusion

Okay, now we know that there is no need to panic if you made a mistake while naming your git branch.

We have seen why might need to rename your git branch, how to rename a branch on local, and then how to push it to the remote repository if required.

And always remember to remove the old git branch from the remote to make sure no one uses it.

How to checkout a git tag?

NoviceDev — Fri, 31 Dec 2021 03:42:18 +0000

Git tags are created to mark a release candidate. Because it points directly to a commit in the git history and will not change.

But sometimes we need to checkout a remote tag to our local.

Here is how we can achieve this.

Fetch git tags

The first thing you need is to fetch the git tag to your local. You can do this by using the git fetch command with --all and --tags arguments.

$ git fetch --all --tags

Checkout tag as a branch

The next step is to checkout a specific tag as a branch with git checkout command with the tag name and new branch name.

$ git checkout tags/<tag_name> -b <branch_name>

Now you can test the code from a tag on your local branch and make updates as well.
